Abstract: In a first example embodiment, a control transmission portion of a mmWave communication is received at a user equipment. The control transmission portion is divided into a plurality of control transmission portion sub-regions, each sub-region scheduling a data transmission for a corresponding sub-region of a data transmission portion of the mmWave communication. Then a first of the control transmission portion sub-regions is demodulated and decoded. A receive analog antenna beamforming is armed according to the demodulated and decoded first of the control transmission portion sub-regions. Beamforming is performed on a first sub-region of the data transmission portion of the mmWave communication, the first sub-region of the data transmission portion corresponding to the first of the control transmission portion sub-regions. During the arming and performing, a second of the control transmission portion sub-regions is demodulated and decoded.

Abstract: A system and method of subframe configuration in licensed-assisted access using long-term evolution (LAA-LTE) with carrier aggregation (CA). A wireless device such as an eNodeB (eNB) may transmit control information in a subframe from a secondary cell (SCell) in downlink control information (DCI) to a user equipment (UE). The SCell may operate in an unlicensed band. The control information may indicate at least one of a non-ending subframe in a data burst, an ending subframe, and a duration of the ending subframe. The duration may be one of a predefined number of orthogonal frequency-division multiplexing (OFDM) symbol durations, and the ending subframe may be a partial or full subframe. A partial ending subframe may use a time slot structure in a time division duplexing (TDD) scheme, e.g., downlink pilot time slots (DwPTS). The eNB may then transmit to the UE data in the subframe according to the control information.

Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.

Abstract: Various methods and systems are provided to provide for Channel State Information (CSI) feedback of hybrid beamforming. In a first example embodiment, a method for signaling a beamforming reference signal (BFRS) is provided. A resource block is created for the BFRS, the resource block containing a plurality of resource elements, each resource element defined by a time-frequency resource within one subcarrier and one multiplexing symbol. A total number of analog transmit beams for the BFRS is then determined, along with grouping information for the analog transmit beams for the BFRS. Then, the resource block, the total number of analog beams, and the grouping information are transmitted from a first network controller to a user equipment (UE). Then the BFRS is transmitted from the first network controller to the UE.

Abstract: Measurements and Channel State Information (CSI) feedback are configured using communications between a network and user equipment (UE). The communications includes a first signaling from a network component to the UE indicating one or more reference signal (RS) resource configurations, a second signaling indicating one or more interference measurement (IM) resource configurations, and a third signaling indicating a CSI report configuration, wherein the CSI report configuration indicates a subset of the one or more RS resource configurations and a subset of the one or more IM resource configurations. The UE establishes a RS based measurement according to the subset of the one or more RS resource configurations and an IM according to the subset of the one or more IM resource configurations. The UE then generates and sends to the network a CSI report in accordance with the CSI report configuration and using the RS based measurement and the IM.
